Continue readingThe lowest-barrier networking certifications for complete beginners — CCST Networking, Network+ and CCNA compared, with a sensible order to take them.

"Just do the CCNA — everything below it is a waste of money." You will hear this in every networking forum, usually from someone who already had two years of helpdesk experience when they sat it. For a genuine beginner — no IT job, no lab, no idea what a subnet mask does — that advice skips the question that actually matters: not which certification is most respected, but which one can you realistically pass from where you stand, and does it lead somewhere? This guide answers that question, working up from the lowest barrier to entry.
Short answer: the easiest credible networking certifications for a true beginner, in ascending order of difficulty, are the Cisco Certified Support Technician — Networking (CCST Networking, exam 100-150, US $125), then CompTIA Network+ (N10-009, US $399), then the Cisco Certified Network Associate (CCNA, 200-301, US $300). None has any prerequisites. Most beginners should treat CCST as optional, choose either Network+ or CCNA as their first serious certification, and pick between those two based on budget, confidence, and whether they are targeting general IT support or network-specific roles.
This article stays at the beginner end of the ladder deliberately. If you are already certified and wondering what the expert tiers look like, that is the territory of our companion piece on the hardest networking certification exams.
The Cisco Certified Support Technician (CCST) Networking certification is Cisco's entry-level credential, positioned explicitly below the CCNA and delivered through Certiport (a Pearson VUE company) rather than through Pearson VUE's main channel — which in practice means it is often taken at schools and colleges. The exam (100-150) runs about 50 minutes, uses multiple-choice, multi-select and drag-and-drop questions, and costs US $125, varying by region. It has no prerequisites and is aimed squarely at students and career changers.
Its six domains — standards and concepts; addressing and subnet formats; endpoints and media types; infrastructure; diagnosing problems; security — read like the first third of a CCNA syllabus, which is exactly the point. As a first exam experience it is low-cost, short, and confidence-building. Two honest caveats: employer recognition is thinner than for Network+ or CCNA, and Cisco's pages do not clearly publish a validity period for CCST, so check the official Certiport and Cisco CCST pages for current renewal rules rather than assuming it behaves like Cisco's three-year certifications.
Best for: students, complete career changers who want a cheap proof-of-concept that networking suits them, and anyone who finds a 120-minute exam intimidating as a first outing.
CompTIA Network+ (current version N10-009, launched June 2024) is the classic "first networking certification": vendor-neutral, no prerequisites, and pitched at foundational breadth rather than configuration depth. The exam allows up to 90 questions — multiple-choice plus performance-based items — in 90 minutes, with a passing score of 720 on a 100–900 scale. Unlike Cisco, CompTIA publishes that passing score, which makes study progress far easier to measure; that transparency is a genuinely underrated reason Network+ feels easier. It costs US $399 direct from CompTIA following a June 2026 price increase, though discounted vouchers are commonly available. The certification is valid for three years and renewed through CompTIA's continuing-education programme (30 CEUs for Network+).
Because it is vendor-neutral, Network+ teaches concepts — models, protocols, media, troubleshooting method — without tying them to one company's command line. It does not go as deep as CCNA into hands-on device configuration, and that shallower depth is precisely what makes it the more passable first exam for someone with no experience.
Best for: beginners heading into general IT support or helpdesk roles first, people who want maximum flexibility about which vendor ecosystem they eventually join, and anyone whose employer reimburses CompTIA exams.
The CCNA (single exam, 200-301, exam topics v1.1) is an associate-level certification, and calling it easy would mislead you: it is the most demanding exam on this list, with 120 minutes of multiple-choice, drag-and-drop and lab-style items covering routing, switching, IP addressing, security fundamentals, wireless, and — since the 2024 v1.1 update — automation, cloud network management and generative-AI awareness. Cisco publishes neither the question count nor the passing score, suggests a year or more of network experience, and charges US $300 per attempt, with a five-day wait and the full fee again if you fail. It is valid for three years, renewable by exam or 30 Continuing Education credits.
It earns its place on a beginners' list for one reason: there are no formal prerequisites, and it is the single most recognised credential for actual network roles — network technician, network support, junior network engineer. Beginners do pass it from a standing start; the common community estimate is around three to six months of part-time study for someone with no experience, though no official figure exists. The price of skipping straight to CCNA is a longer, steeper study phase and a costlier exam day if you misjudge your readiness — which is where free practice material earns its keep; our guide to free networking practice tests maps out those sources.
Best for: committed career changers targeting network-specific roles, and anyone who learns well from hands-on lab work (the free Packet Tracer simulator covers most CCNA practice needs).
Juniper's associate-level JNCIA is the natural first rung for careers in Juniper-heavy environments, and it belongs on any list of entry-level networking certifications. This guide does not quote its current format or fee — verify those on Juniper's official certification pages — but the strategic advice is simple: choose it first only if you already know your target employers run Juniper; otherwise the three options above serve a beginner better because their recognition is broader.
For most readers the choice collapses to these two, so here is the comparison that matters:
| Factor | CompTIA Network+ (N10-009) | Cisco CCNA (200-301) |
|---|---|---|
| Difficulty for a beginner | Moderate — broad but shallower; published pass mark (720/900) | Hard — deeper, includes lab-style items; no published pass mark or question count |
| Prerequisites | None | None formal; Cisco suggests 1+ years' experience |
| Cost (US list) | $399 (vouchers often less; varies by country) | $300 (varies by country; full fee on retakes) |
| Exam format | Up to 90 questions, 90 minutes | 120 minutes; mixed item types incl. simulations |
| Best for | General IT support, vendor flexibility | Network-specific roles, Cisco environments |
| Career path | Helpdesk → support → specialisation | Network technician → engineer → CCNP/CCIE ladder |
| Skills emphasis | Vendor-neutral concepts and troubleshooting | Configuration-level depth on routing and switching |
| Validity/renewal | 3 years; 30 CompTIA CEUs | 3 years; exam or 30 Cisco CE credits |
Neither is universally better. Take Network+ first if you have zero IT background, need an achievable win within a few months, or are not yet sure networking (rather than security, cloud or support generally) is your destination. Go straight to CCNA if you are certain about a network career, can commit to several months of study with regular lab time, and can afford a $300 exam where a misjudged attempt costs the full fee again. Taking both, Network+ then CCNA, is a legitimate path — the overlap means your Network+ study is not wasted — but it is a spending decision, not a requirement: no rule obliges you to climb every rung.
Among credible, employer-visible options, CCST Networking is the lowest barrier: a roughly 50-minute, $125 exam with no prerequisites, covering fundamentals. "Easiest" still assumes study — it examines subnetting and diagnostics, not trivia.
Yes. CCST, Network+ and CCNA all have no formal prerequisites. Experience suggestions (such as Cisco's one-plus years for CCNA) describe the typical comfortable candidate, not an entry rule.
No — there is no prerequisite relationship in either direction. Network+ first simply gives you a gentler slope and an earlier win; skipping it saves money and time if you can sustain a longer CCNA study campaign.
For CCST or Network+, a few months of consistent part-time study is a common pattern; for CCNA from zero, community experience clusters around three to six months part-time, though no official figure exists and your available hours per week dominate everything else.
The easiest networking certification is the one that fits your starting point: CCST if you need a low-cost confidence builder, Network+ if you want the most passable serious credential with the broadest flexibility, CCNA if you are committed to network roles and willing to earn the harder badge first time out. All three are prerequisite-free, all three are beginner-attainable, and none of them locks you out of the others. Pick one, put a date on it, and start with the free material — the full exam directory is the quickest way to find sample questions for whichever rung you choose.
